Abstract

　アンテナの持つ偏波特性を切り替えることができ、時々刻々と変化する基地局と端末間の偏波状況により低下、又は変動する受信信号に対して通信容量の減少を防いで、多様な偏波環境、使用形態においても伝送容量を向上させることのできるアンテナ装置及び通信装置。アンテナ装置（１１０）は、第１の偏波方向用の複数の第１のアンテナ素子（１１１，１１２）と、第１の偏波方向と直交する方向に設けられた第２のアンテナ素子（１２１）と、複数の第１のアンテナ素子（１１１，１１２）と第２のアンテナ素子（１２１）の接続を切り替える複数のスイッチ（１３１，１３２）と、複数の第１のアンテナ素子（１１１，１１２）にそれぞれ設けられた給電部（１４１，１４２）とを備える。
